Metron Fire Pump Controllers conform to the
latest requirements of Chapter 10, National Fire
Protection Association Pamphlet 20, Standard
for Centrifugal Fire Pumps as adopted by
Underwriters Laboratories and Factory Mutual.
Sizes range from 15 to 600 horsepower, 200 to
600 volts, 60 Hz. These controllers are used on
reduced voltage type installations using a solid
state starter for “Soft” starting and “Soft” stopping
of electric motors.
Only the highest quality components, all UL listed
or UL recognized, are used throughout to assure
the best possible reliability. The cabinet is
fabricated of heavy gauge reinforced steel with
drip-proof hood. All field wiring and service
connections may be made from the front, allowing
the controller to be mounted flush against a wall.
The controller is completely wired, assembled, and
tested at the factory before shipment, and ready
for immediate installation.

data logs for storing system data that is readable through
the OID or copied to a computer equipped with an SD
card reader. The 2 data logs are as follows:
HIGH DISCHARGE PRESSURE
NO LOAD CONDITION
Options
Option H: Space Heater
If the ambient atmosphere is especially damp, a space
heater rated at 100 watts may be supplied to reduce
moisture in the cabinet. A thermostat is supplied as
standard with this option. A humidistat may be
substituted if specified.
Option W: Omit Legs
For systems where the controller is mounted on a
common skid with the pump and motor, the legs of the
controller may be omitted, 3” (76.2mm) channels or wall
mounting brackets can be supplied. If specified, lifting
eyes may also be supplied.
Enclosure
The following NEMA type enclosures are also available:
3R, 4, 4X (Painted Cold Rolled Steel), 4X (304 or 316
Stainless Steel), and 12
Pressure Log: The pressure log provides a continuous
pressure record for 30 days. The pressure log samples
shall be time and date stamped and stored in permanent
non-volatile SD memory card. The pressure log can be
searched by each sample, by minute, or by hour through
the OID.
Event Log: The event log will store up to 300 of the most
current events. These events can include, but is not
limited to, any of the following events/alarms:
PUMP RUNNING
POWER AVAILABLE
PHASE REVERSAL
MOTOR OVERLOAD
REMOTE START
LOCAL START
PUMP ON DEMAND
SYSTEM FAULT
PRESSURE TRANSDUCER FAULT
PUMP FAILED TO START
LOW INTAKE SHUTDOWN ALARM
SUPERVISORY POWER FAILURE
LOW PRESSURE
AUTO WEEKLY TEST START
UNDER FREQUENCY
OVER FREQUENCY
LOW ZONE / HIGH ZONE CONTACTS

Standard and Optional Features
Standard Features
Function - The MP700 series Soft Start electric fire
pump controllers utilizes a state of the art solid state
motor controller. The motor voltage is raised to an initial
torque value. This is an adjustable value of locked rotor
torque. The motor voltage is gradually increased during
the acceleration ramp time. The acceleration ramp time
is set to 10 seconds as required by NFPA 20, but it is
adjustable from approximately 3 to 30 seconds.
After a minimum run period and all starting causes have
returned to normal, the solid state controller will initiate a
stop sequence. This function will reduce surges in the
pumping system during stopping of a centrifugal pump by
smoothly decelerating the motor at a selectable rate.
This will reduce the possibility of surges occurring in the
system.
